Berkin Elvan, who has been in a coma since June 2013 after being struck in the head by a gas canister during a police crackdown on protesters, died March 11, his family announced via Twitter.

The young teenager, the eighth person to be killed in the Gezi Park protests, went into a coma after sustaining a head injury from a gas canister as he went to buy bread during a police crackdown in Istanbul’s Okmeydanı neighborhood last June. Elvan has since become one of the prime symbols violence faced by protesters throughout the nationwide Gezi demonstrations.

He had only turned 15 in January while still in a coma. A ceremony will be held at a cemevi in Okmeydanı before the burial in Feriköy cemetery on March 12.

Scores of people gathered in front of the hospital where Elvan was convalescent for over nine months, in a show of solidarity with the family upon calls on social media.

Tension rose between a group of demonstrators and the police, which again resorted to tear gas regardless of the fact that the hospital's entrance was nearby.

“Riot police arrived in front of the hospital as the funeral was ongoing to be sent to the forensics department. Some people also went that way and protested against the police. A scuffle occurred. The police officers did not restrain themselves at all from using gas. They once again used disproportionate force,” said Republican People’s Party’s(CHP) Istanbul lawmaker Melda Onur, who was participating in the vigil. "Tear gas even entered inside the hospital," she added.

Onur also said a child was brought into the hospital after being injured due a tear gas canister.

Another man, who was going to the hospital to visit his sick wife, was also injured after being hit in his head by a tear gas canister.

The teenager’s parents were shattered when they joined activists keeping vigil for Berkin.

“It is not Allah who has taken my son away. It is [Prime Minister Recep] Tayyip Erdoğan,” said the mother, Gülsüm Elvan.

Erdoğan had memorably praised police for “heroic action” during the Gezi resistance last June, despite the murdered victims and serious injuries sustained due to the repeated brutal crackdowns on protesters.

The mother of Ali İsmail Korkmaz, a 19-year-old protester who died after being beaten during the Gezi protests in Eskişehir by a group of men including plainclothed police officers, came to the hospital to offer her condolences to Elvan's family.

Lawyers representing the family had said Elvan’s condition worsened over the last week, with his weight dropping to 16 kilos from 45 kilos.

Elvan suffered an epileptic fit on March 6, his heart stopped a day later, and on March 9 doctors diagnosed an air pocket in his lungs.

“His young body resisted for 267 days against the damage caused by the gas canister fired by the police, the same way our people resisted against fascism. But that resistance has been decreasing gradually and the damage to his inner organs is growing due to the fact that his brain functions are very low," a statement from the lawyers released on March 9 said.

In a first for a government official, President Abdullah Gül had contacted the family on March 10 as a police intervention was ongoing against a vigil held in front of the hospital in Istanbul’s Okmeydanı neighborhood.
